Inventor: GOTO TAKAHARU
IPC: F16J1/02
Filed: 1989-12-20
Abstract: PURPOSE:To enable the optional setting of the contact area distribution of a skirt part to a cylinder by forming a streak extended circumferentially at the skirt part of a piston, and changing its depth in the peripheral direction so as to dispose its main contact region, small in the opening width of the streak, at the skirt part. CONSTITUTION:The skirt part 6 of a piston 1 is provided with a streak formed along its circumferential direction. Mainly the depth of the streak 11 is changed in the peripheral direction so as to dispose a main contact region 9, relatively small in the opening width of the streak 11, at the skirt part 6. The main contact region is provided with an upper part 9a having a relatively large width Wa in the peripheral direction and a lower part 9b having a relatively small width Wb. The depth of the streak 11 is changed in its cross section from an auxiliary contact region to the main contact region at the specified ratio: from h0 to h9. The appropriate distribution of the contact area of the skirt part 6 to a cylinder can be thereby set optionally and simply.

Title: Treatment of soot
Inventor: YOSHIDA TSUNEYUKI
IPC: A62D101/08
Filed: 1993-12-27
Abstract: PURPOSE:To certainly prevent the elution of heavy metal from treated matter by easily, efficiently and safely treating soot. CONSTITUTION:Phosphoric acid and/or phosphate and silicic acid and/or silicate are added to soot to be kneaded therewith. Since a substance generating harmful gas is not contained in a chemical agent to be used, there is no possibility of the generation of harmful gas at the time of the addition of the chemical agent. Silicic acid and silicate form a compd. extremely low in solubulity along with heavy metal in an especially high pH region while phosphoric acid and phosphate form the above mentioned compd. along with heavy metal in an especially low pH region. By together using both chemical agents, the elution of heavy metal can be certainly prevented over a wide pH range.

Abstract: PURPOSE:To form carbon film attached to a surface discontinuous, and prevent flashover by providing plural circular grooves having a V-or U-letter shaped cross sectional surface having specified width and depth at specified positions of a leg length part of an insulation insulator. CONSTITUTION:An insulation insulator 2 is provided with a small diameter leg length part 22 on the forward end side, a middle diameter waist part 23 in the middle, and a middle diameter head part 26 having corrugation 25 on the back end side. Three circular grooves 5 at a distance of less than 6.0mm from the waist part 23, and of a width of 0.3mm or more and less than 1.0mm and a depth of 0.3mm or more and less than 1.0mm having a V-letter or U-letter shape cross sectional surface are formed at the leg length part 22. Formation positions of the circular grooves 25 are limited to be within 6.0mm from the waist part 23 because the insulator 2 becomes easy to be broken by thermal stress if they are formed on the forward end side of it. By specifying the width and depth of the circular groove 5, carbon film attached to a surface becomes discontinuous, thereby generation of inner flashover or flying spark mistake can be prevented.
